GNSS Precipitable Water Vapor for Weather Forecasting

(Left): The continuous near real-time (NRT) PWV (with latency of 18~60 minutes, depending on availability of RINEX data) product in US and global networks. (Right): Same with left map but magnified plots for CONUS. Currently we are processing 1,362 US and global stations (data arrived within cut-off time is processed in each scheduled processing time), and generate NRT PWV products for weather forecast.

The continuous NRT RTNet PWV processing system service can include GNSS stations (RINEX or real-time data) at any locations, process the data with high quality multi GNSS satellite clock products, and provide PWV and slant delay prodcuts to users.
